Long-legged Myotis
|
Myotis volans
Scientific name translation: "Mouse-eared", "Flying" |
Description
Long-legged myotis, named for their longer tibia in comparison to other Myotis species, can be distinguished from other Myotis species by the patches of fur on their wings that extends to the elbow, the presence of a keeled calcar, overall size, and their short, rounded ears. M. volans have a head and body length that ranges from 45–63 mm, tail length that ranges from 40–50 mm, ear length that ranges from 12–15 mm, and a forearm length that ranges from 38–42 mm.
Distribution
This species is associated with forested habitats, especially coniferous forests, but may also be found in riparian forests, mixed deciduous forests, and juniper scrub. It is a western species with a limited distribution in South Dakota on the west side of the state.
Ecology
Long-legged myotis will use a variety of roosts such as rocky crevices, caves, mines, trees, or human-made structures. Bats will emerge from hibernacula in early spring, with pups being born as early as May. Pregnant females may form groups of up to several dozen individuals, while males are often solitary during the maternity season.
